Abstract
A method for reducing coherent and random noise in seismic data is disclosed. The method includes, obtaining a plurality of time-space waveforms () and generating a plurality of overlapping time-space windows by dividing the plurality of time-space waveforms (). For each overlapping time-space window, the method further includes determining a transformed window from the time-space window (), determining a coherent noise window from the transformed window by performing a first soft thresholding based on a predetermined parameter range (), determining a random noise window from the transformed window by performing a second soft thresholding (), and determining a time-space filtered window based, at least in part, on subtracting the coherent noise window and the random noise window from the overlapping time-space window (), determining a plurality of time-space filtered waveforms by assembling the time-space filtered window for each of the plurality of overlapping time-space windows (). It also includes a non-transitory computer readable memory and a system.
